Using r to pull data from app.powerbi.com

I've been searching and searching trying to find out whether or not something can be done.

There is a Power BI report within my company that I have access to. For reasons to complicated to explain, I need to reproduce some of the visualizations in my own Power BI dashboard.

Currently, what I have to do is click on a graph and export the underlying data, which comes as a csv file. I have to do this manually for 3 different plots. I know Power BI can do some web scraping, but I get access issues, if I try to do this using Power BI. I've learned from our IT, that in order for me to do this, I'd have to be named as a co-owner of the site I'm scraping. I'm not sure that can happen.

Is there a way I could use R from my end to export the underlying data for me?

To be clear--I can manually export the underlying data I need just accessing the site through my browser. I'd like to be able to have either R or Power BI do this for me.
